Definitions

  • FIG. 1 shows a longitudinal section through an electric machine 10, here in the embodiment as a generator or alternator for motor vehicles.
  • This electric machine 10 has u. a. a two-part housing 13, which consists of a first bearing plate 13.1 and a second bearing plate 13.2.
  • the bearing plate 13.1 and the bearing plate 13.2 take in a so-called stator 16, on the one hand consists of a substantially annular stator iron 17, and in whose radially inwardly directed, axially extending grooves, a stator winding 18 is inserted.
  • This annular stator 16 surrounds with its radially inwardly directed grooved surface a rotor 20 which is formed as a claw-pole rotor.
  • the rotor 20 is u. a.
  • the rotor 20 is rotatably supported in the respective end shields 13.1 and 13.2, respectively, by means of a shaft 27 and one respective rolling bearing 28 located on each side of the rotor.
  • the rotor 20 has a total of two axial end faces, on each of which a fan 30 is attached.
  • This fan 30 essentially consists of a plate-shaped or disk-shaped section from which fan blades originate in a known manner.
  • These fans 30 serve, via openings 40 in the end shields 13.1 and 13.2 an air exchange between the outside of the to allow electric machine 10 and the interior of the electric machine 10.
  • the openings 40 are provided essentially at the axial ends of the end shields 13.1 and 13.2, via which cooling air is sucked into the interior of the electric machine 10 by means of the fan 30.
  • This cooling air is accelerated by the rotation of the fan 30 radially outward, so that they can pass through the cool air-permeable winding overhang 45 therethrough. By this effect, the winding overhang 45 is cooled.
  • the cooling air takes after passing through the winding overhang 45 or after flowing around this winding overhang 45 a way to the outside radially, not shown here in this figure 1 openings.
  • a protective cap 47 which protects various components against environmental influences.
  • this protective cap 47 covers, for example, a so-called slip ring assembly 49, which serves to supply a field winding 51 with exciter current.
  • a heat sink 53 Around this slip ring assembly 49 around a heat sink 53 is arranged, which acts here as a plus heat sink.
  • the bearing plate acts 13.2.
  • a connection plate 56 is arranged, which serves to connect arranged in the bearing plate 13.2 minus diodes 58 and not shown here in this illustration plus diodes in the heat sink 53 together and thus represent a known bridge circuit.

  • the stator winding 18 has an inner winding head 130 which has coil side connectors 133, which connect coil sides 136, which are shown symbolically in FIG.
  • the inner winding head 130 has a certain axial extension of a stator iron 17 on starting.
  • the coil connectors 126 of different partial phase windings 120a, 120b intersect in the winding head 139. formed crossing point 142 is so far away from the stator iron 17 that the inner winding head 130 between the intersection 142 and the stator iron 17 is located.
  • FIG. 4b shows the winding head 130 from its axial side in a highly schematic manner.
  • the inner winding head 130 is visualized by two continuous lines.
  • Coil connectors 126a, 126b are shown by simple lines.
  • Superimposed lines illustrate intersections 142.
  • the coil connectors 126 have a trapezoidal shape with two oblique sections 145 each and a straight section 148 therebetween.

  • the coil connectors 126 of the three phase windings 120 with their straight sections 148 are arranged in two radial layers 160, 161. Two pairs of coil connectors 126 are each disposed entirely within an inner 160 and an outer radial layer 161, respectively.
